There’s a certain insidiousness to the way glaucoma — a group of eye diseases that damage the optic nerve — can snatch away a person’s vision.
That damage can be so slow that people may never notice until it is too late, and the long term impacts, like loss of peripheral vision, blind spots, and blindness, have set in.
Glaucoma impacts tens of millions of people globally, and is the second leading cause of blindness, after cataracts. Now, Purdue University researchers have developed smart contact lenses that may help save people’s sight.
